ANTIGLARE ATTACHMENT FOR VEHICLE HEADLIGHTS Filed 'Aug. 27, 1929 2 Sheets-Sheet 2 7 I /7 a H a Inventor A iiorney rte Patented Feha lh, lddl BRUCE B. DYE AND FRANK C. MCDOUGALL, 0E BONNER SPRINGS, KANSAS ANTIGLABE ATTACHMENT FOR, VEHICLE EEADLIGHTS Application filled August 27, 1929. Serial No. 388,723.

The present invention relates to an antiglere device for vehicle headlights, and has as its primary object the provision of a device capable of application to an automobile, aeroplane, or similar vehicle headlight which will give greater vision ahead of the vehicle, Will reduce the glare of" the headlights so as not to blind the operators of vehicles approaching from in front of the vehicle equipped with this device, thus promoting safe driving under the shove-enumerated circumstances.

A still further object of the invention is to provide a device of this nature, which may be attached tn the cenventional headlight cesmg against the lens of the headlight to project forwardly from the lamp casing said device con'iprising s plurality of concentric rings providing spaced apart deflecting surfaces to arrest cb ecticnal direct reys which would otherwise diver e widel directl in front of the headlight.

@ther objects and advantages of the invention will become apparent during; at study of the following description, taken in connectien with the accompanying drawings, wherein:

Figure 1 is s front elevation of s headlight equipped with the anti-glare and Eng eliminater device.

With reference more in detail to the drawings it will he observed that the reference character 5 designates genersliy s ieinp cesingci ccnventicnal cc strncticn d the parahe is refiecter member which is else cenventienel and srrsnged in the casing in the nsnel well known insnnen The lamp hnih is designated g,e-rnarsll" the reference character '2' the lens h the re erence character 8, the flanged. ice 2 mining ring is designated as at 9'.

structure is ccnventiensl end is best shcwn weirdly or tensed the outer end Seen and illustrated in detail in order that one may obtain a clear understanding of the applicetion of the present invention.

The invention per se consists in a plurality of concentric reflecting bands or rings 10 adapted to be positioned around and for- Wardly of the lens 8, said bands or rings" 10 bein% spaced apart from one another as clear fishown. The outer hand or ring which outer and or ring is of the greatest diameter, is provided on its inner edge with an out standing peripheral fisnge 11. The flange ii is adapted to be disposed against the outer face of the lamp lens 8 adjacent the periphersl flange 11. The flange 11 is adapted to he disposed against the outer face of the lamp lens t3 adjacent the peripheral edge of the rim as shown to advantage in Figure 5.

The lens retaining rim 9 has its vertical flange 9 disposed against the flange 11, the

material at the hand 9 forming the fisnge 9 is bent upon itself upwardly and then ex tended leterelly as at 12 for rest upon the peripheral edge of the lens 8 end the said ring flange 11, as else shown to advantage in Figure 5. lteervvsrdly of the lens 8 and positisned between the lens and the enter flanged end of the parabolic reflector 6 is the usnsl necking ring 13. For maintaining the ienieimng bands or rings-1O spaced forwardly frem the lens 8 and speced irszn ene enether, we provide a "peir of spacer members signzited generally hy the reference cherecter it.

'The spacer members it are substantially of lishsned configuration and there ere two of such spscer members 1 1-, as illustrated to advantage in l ignrel. @ne cf the spacer members M- is disposed vertically and the, other horizcntslly. Since the ccnstruetion of both oi eel it ishelieved that s detaiied descripticn of one will snide-e.

Each cf the said specer inernhers are provided on rest-weirdly extend enter edges with stepped pic-ejections 15. These stepned. 'prejecticns 15 recede resin of the inenihers from the apex cf the members. At its apex, the members it are prcvided with the specs? members ere identh relatively large step 16 between the adjacent steps, the members 14 are attached at 17. The'inembers 14 are also provided at their apex with an inwardly extending notch or slit 18 which slit 18 extends inwardly from the rear edge of said members 14.

At their outer extremities, each of the members 14 are rovided with oppositely extending lateral anges 19-19.

In practice, one of the members 14 is disposed vertically and is positioned between the lens 8 and the rings, the pro'ection 16 at the apex of the vertical mem er being received 1n the center or smallest of the rings 10, and this projection 16 extends diametricall of the rin and is equal to the diameter 0 the ring, w ile the steps 15 project into the next adjacent rings, these projections 15 corresponding to the diameters of the rings, and the inner edges of the rings or hands 10 extend into the slits 17 as will be apparent from a study of Figure 3.

The second of the spacer membersl i is dis posed horizontally, said horizontal and vertical members 14 being inter-connected with one another where they intersect at their apices, through the medium of the slots or slits 18 as is apparent. Of course, the distance from one end flange 19 to the other of the respective spacer members 14 is substantially equal to the diameter of the outer or flanged ringl 10, which inner flanged ring is of course t e largest of the rings, and the flanges 19 are disposed against the inner face of said ring as is also shown to advantage in Figure 3.

Therefore, it will be seen that the rings are maintained in concentric spaced relation and that the rings graduate in iameter from the apex to the extremities of the V-shaped spacer members.

The bands or rings 10 on their outer face ma be of any color desired to correspond wit the color of the lamp casing, but the inner faces of the rings or hands are preferably coated with a white paint or enamel so as to modify the light rays as they pass through the rings to issue therefrom.

It is believed that from a study of the foregoing description, taken in connection with the accom anying drawings, a clear understanding 0 the operation, construction, utility and advantages of a device of this nature will be had, and a more detailed description thereof is deemed unnecessary.

Even though we have herein shown and described the preferred embodiment of our invention, it is to be understood that the same is susceptible to changes fully comprehended bythe spirit of the invention as herem described, and thescope of the appended claims.

Having thus described our invention, what we wish to claim is:

1. In a device of the class describechthe rece 'ng inwardly from one another towards the ends of said member, and a plurality ofbands positioned around said member, and said pro'ections adapted to be disposed between a jacent ban s for maintaining said bands in spaced relation.

2. A headli ht having in combination, a pair of crosse spacing members, said members being connected together intermediate their ends, means provided on the outer ends of said members for enga ement with the lens retaining ring of the ieadli ht for securing said members forwardly o the headlight, a plurality of concentrically arranged bands, said spacin members respectively provided on one e ge thereof wit a plurality of spaced pro'ections extending between adjacent ban for retaining said bands in spaced relation, and the projection of the respective members receding inwardly from one another toward the ends of said members.

In testimony whereof they aifix their signatures.
